Question

what is the work of RBCs?​

Answer 1

Answer:

Red blood cells (RBCs), also known as erythrocytes, have two main functions:

1. To pick up oxygen from the lungs and deliver it to tissues elsewhere.

2. To pick up carbon dioxide from other tissues and unload it in the lungs.

Answer 2

Answer:

Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
